Hi Jonathan,
On a side note, my predicted values are consistently about $50,000 higher
than the ones you got from what were using. Since I don't know what exactly
your tool is doing, I can't tell you why that is).

If you want to take into account the fact that it's actually a time series,
R has plenty of tools for that too.

can u please tell me how u got $50,000 values,how u got that values what
methods u have applied .


Thanks and Regards
Chinna.
